The term "equipment instance" refers to an equipment record in a Citect SCADA project.
When you add an equipment instance to your project, you specify a location for it within the project's equipment hierarchy. This is reflected in the complete equipment name (where a period (.) can be used to indicate levels in the hierarchy). This location can then be used to refer to the variable tags, alarms and trends that are associated with the equipment instance.
An equipment instance contains a set of properties that may be used in the generation of tags, alarms and trends for that instance. These properties can also be used at runtime in conjunction with the equipment browse functions.
Every equipment instance includes a predefined set of properties that are common to all equipment instances (see Manually Define Equipment).
If an equipment instance has been created using an equipment type as a template, it will include additional properties that reflect the items and custom parameters specified in the associated equipment type. Each instance maintains an association with the equipment type from which it was created, allowing equipment type changes to be instantiated across all related instances.
To create equipment instances from an equipment type, you use the Equipment Editor (see Using Equipment Editor to Generate Tags).
Note: Equipment does not need to be associated with an equipment type. This scenario is typical in projects where equipment associations have been configured for existing variable tags. See Define an Equipment Association for an Existing Tag.
